Phil Daniels (New Tricks, Eastenders), Donald Sumpter (Game Of Thrones) and Emma Rigby (Once Upon A Time In Wonderland) have been confirmed as guest stars in the upcoming series of popular detective drama, Endeavour, which is set to air next month.

Set in 1968, the new series begins with Morse having finally passed his Sergeant’s exams, as Oxford City Police merges into Thames Valley Constabulary.

Joan Thursday (Sara Vickers) has returned to Oxford, but much is unresolved following her disappearance the previous year and Endeavour’s unexpected proposal.

Also reprising their roles in the upcoming drama are Sean Rigby (Gunpowder), Dakota Blue Richards (Skins), Abigail Thaw (I Want My Wife Back), James Bradshaw (Primeval) and Caroline O’Neill (Last Tango In Halifax). Poldark star Lewis Peek has also joined the cast as a regular.

The new films have been executive produced by Russell Lewis, alongside former Endeavour producer Tom Mullens, Mammoth Screen’s Managing Director Damien Timmer and Rebecca Eaton for WGBH, with John Phillips (Stan Lee’s Lucky Man) and Neil Duncan (Fortitude) producing.

Tom Mullens says: “It’s an honour to have so many great names joining us for the new series.

“And across the six films we have many compelling worlds to explore – from Hollywood glamour and Egyptian curses to espionage amidst European sporting events – which we hope will continue to excite and entertain.”
